woodju3, I have made lot's of rag quilts, and I use warm and natural in all of them. Before I started, I read a lot of how to instructions and they all said to cut the batting smaller, and to NOT catch the batting in the seam. In other words, the only quilting holding the square together was the "X" in the center. I didn't want to do mine that way, so I cut he batting so a small amount of it was caught up in the seam, but didn't show after I fringed it. It makes for a stronger square. I saw a rag quilt once that didn't have the batting (polyester) caught up in the seam, and the batting had shifted after washing. I know most people don't sew in the batting, and are happy with it, but I just choose to do mine differently.
